Hi there,
I am trying to add Mosquitto (MQTT) as a cheribuild target. This is my current Python script:
from .crosscompileproject import CrossCompileCMakeProject, GitRepositoryfrom ...config.compilation_targets import CompilationTargets
class BuildMqtt(CrossCompileCMakeProject): target = "mqtt" repository = GitRepository("">github.com/.../mosquitto") supported_architectures = CompilationTargets.ALL_FREEBSD_AND_CHERIBSD_TARGETS + [CompilationTargets.NATIVE]
When running ./cheribuild mqtt-morello-purecap to build the target, I run into this error message:
CMake Error at man/CMakeLists.txt:29 (message): xsltproc not found: manpages cannot be built
-- Configuring incomplete, errors occurred!
Looking at the MQTT Git repository here and in the "Building from source" section, I can add the CMake option "WITH_DOCS=no" which disables checking for the optional build dependency xsltproc to generate man pages which I don't need. With these changes my build script now looks like this:
def setup(self): super().setup() self.add_cmake_options(WITH_DOCS=no)
Now when I attempt to run ./cheribuild.py mqtt-morello-purecap again, I am presented with multiple errors:
Traceback (most recent call last): File "./cheribuild.py", line 42, in <module> main() File "/home/ubuntu/cheribuild/pycheribuild/__main__.py", line 258, in main run_and_kill_children_on_exit(real_main) File "/home/ubuntu/cheribuild/pycheribuild/processutils.py", line 771, in run_and_kill_children_on_exit fn() File "/home/ubuntu/cheribuild/pycheribuild/__main__.py", line 248, in real_main target_manager.run(cheri_config) File "/home/ubuntu/cheribuild/pycheribuild/targets.py", line 435, in run target.execute(config) File "/home/ubuntu/cheribuild/pycheribuild/targets.py", line 129, in execute self._do_run(config, msg="Built", func=lambda project: project.process()) File "/home/ubuntu/cheribuild/pycheribuild/targets.py", line 107, in _do_run project.setup() File "/home/ubuntu/cheribuild/pycheribuild/projects/cross/mqtt.py", line 11, in setup self.add_cmake_options(WITH_DOCS=no)NameError: name 'no' is not defined
Any ideas why this section below in particular is occurring? Or any ideas on how to skip the checking for the xsltproc optional dependency?

Thanks!
It's always been that https://github.com/eclipse/mosquitto/commit/3163cf2d709e7b021867aec2e811331991ad097a. Someone just put the wrong thing in the README, presumably wasn't thinking and assumed it followed the same pattern as all the other options which do use WITH_FOO.
Ah. It's WITH_DOCS for the Makefile, and the README talks about make. For CMake it just says "Equivalent options for enabling/disabling features are available when using the CMake build".

Thanks for the clarification Jessica :) It seems to build perfectly now
